VEHICLE-WHEEL HUB.

SPECIFICATION forming part of Letters Patent No. 227,806, dated May 18,1880.

(No model.)

To all whom it may concern:

Be it known that DANIEL MAY, of Lumberton, in the county of Robeson andState of North Carolina, have invented certain new and usefulImprovements in Hubs for Vehicles; and 1 do hereby declare that thefollowing is a full, clear, and exact description thereof, which willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the aecompanyin"drawings, which form apart of this specification, and in which- Figure l is a perspective viewof the axlebox with its rigid hub and flanges. Fig. 2 is a similar viewof the detachable clampingplate. Fig. 3 is an axial sect-ion of the hubwith spokes inserted, and Fig. 4 is a crosssection of the same.

Similar letters of reference indicate corresponding parts in all thefigures.

The object of my invention is to produce a hub for vehicles which shallconsist of few parts simply put together, so as to combine eheapness ofmanufacture with strength and durability, and which admits of thedetaching of the spokes and of their reinsert-ion in a simple and easymanner, substantially as hereinafter more fully set forth.

In the drawings, A is the axle-box, which is castin one piece with therigid circular hubflange a, and provided with a series ofcircumferential ribs or flanges, I) b, extending from flange a outwardto the square section not the axle-box.

B is an annular plate, having a central square aperture, (I, which fitsupon the square section 0, above referred to.

Plate B has on its inner side or face, surrounding its central aperture,(1, a series of circumferential recess sor depressions, (denoted by c c0,) which reg ster with and receive the outward ends of the flanges b.

The spokes l) are tenoned off at their lower ends to [it into the spacesbetween the webs or flanges I) b, and are held tirn'ily in place bybeing clamped sidewise between the annular flange (t and the smooth rimor face of plate B, as will appear more clearly by reference to Fig. 3on the sheet.- of drawings.

The cireuinferential recesses 0 in plate B are made of such a depth asto leave a narrow space (denoted b.v after the plate has been by the nut(l screwed home upon the spokes, which admits of thesebcingtightened intheir seat, as occasion requires, by tightening the nut O, which worksupon the screw-threaded cylindrical tap g of the axle-box. By looseningthis nut and plate B any one or all of the spokes may readily bewithdrawn from the hub.

Having thus described my invention, I claim and desire to secure byLetters Patent of the 'nited States The combination, with the box or hubA, having the flange a, and a reduced portion provided with a series ofradial spaced-apart partitions, b, said reduced portion having anangular extension, 0, beyond the partitions b, and the extension 0provided with a screwthreaded portion. g, of the plate B, with its innorface provided with a concentric series of recesses, c c, coincident withand receiving the free ends of the spoke-partitions I) I), and with thatportion of its same face beyond the recesses 1: fitting against andclamping the spokes, as shown and described.

In testimony that I claim the loregoing as my own I have hereto affixedmy signature in presence of two witnesses.

DANIEL MAY.
